CHECK OR, CLAQK VALVE.

SPECIFICATION forming part of Letters Patent'No. 705,255, dated July'22, 1902.

Application filed January 4:, 1902; Serial No. 88,461. (No model.) I I IT0 at whom it may concern: 1

Be it known that I, FRANK W. LEIDECKER; a citizen of the United States,residing at Marietta, in the county of Washington and State of Ohio,have invented a new and useful Check or Clack Valve, of which thefollowing is a specification.

This invention relates to back pressure valves, commonly known asclack-valves.

The object of the invention is to provide a valve which is freelymovable in its bearings and which has a peculiarly-constructed hingewhich is especially adapted to this formof valve. 7

Figure 1 of the. accompanying drawings represents a plan view ofa'pipe-seotion with this improved clack-valve applied thereto. Fig. 2represents a longitudinal vertical section thereof, the open position ofthe valve being shown in dotted lines. Fig. 3 represents a transversesection taken on line 3 3 perspective view of the valve detached.

The same reference-numerals indicate corresponding parts in all thefigures.

In the form shown in the drawings the valve is shown applied to anexteriorlyscrewthreaded pipe-section 10, which is'adapted to be screwedinto any form of pipe either directly or through the medium of apipe-coupling. It is preferred to make thesevalves in connection withsuch a section, which may be made and sold as a separate article ofmanufacture and applied to any desired pipe with which it is desired touse it, either in a gas=pipe or in a water system.

The pipe-section 10is preferably made with a reducedeXteriorly-screw-threaded portion 11, and near the center an enlargedcollar 12 is formed, which provides an abutting shoulder 13 for theinner end of a pipe to be connected with said reduced portion. Thecollar 12 is preferably provided with angular faces, adapted to beengaged by a suitable wrench for screwing the section 10 into a pipe orpipe-coupling. The front part of the sec tion 10 on the inner side ofthe collar 12 is preferably made slightly larger in diameter than theportion 11 and is also exteriorly screw-threaded to receive'anotherpipeto be attached thereto? This front portion 14 is cut obliquely to itsaxis, as shown in Fig. 2,

to be readily inserted in a pipe.

toform an inclined valve-seat 15. The part above said valve-seat isclosed in to form a ders are rounded to-conform to the shape of thecontour of the section 10 and to adapt it (Not shown.) A valve 20,preferably leaf-shaped and having a beveled or rounded upper face, isprovided at the upper edge thereof with an upwardly and outwardlyextending valve-stem 21, preferably made angular in cross-section andadapted to fit in the opening 18 between thelugs 16 and 17. Theupperends or edges 22 and 23 of the stem 21 are adapted to fit closelyagainst the front lower edges of the lugs 16 and 17. The outer end ofthe stem 21 is connected to or made integral with a rod 24:, extendingat rightangles to said stem and provided at its opposite end withbeveled faces adapted to conform when in position to the contour ofthepipe-section 10. The ends of said rod 24, disposedon opposite sidesof the stem 21, will be designated as 25 and 26.

In assembling the parts the rod 24 of the valve is inserted in thechannel 19, with the end 25 thereof'extending through the closed portionat the back of the lug 16 and the end 26 thereof resting in theopenportion of this channel 19. The valve is then swung downward, and thestem 21 thereof fits in the channel or opening 18 between the lugs 16and 17 and permits the clapper to seat itself on the valve-seat 15. Thevalve is thus locked in position against sidewise movement, whilepermitting it to swing freely up and down or back and forth, accordingto the location of the pipe. Then the section 10 is screwed into a pipe,the inner face of the pipe locks the hinge against accidental upward oroutward movement while permitting it toswing freely in its bearingsformed by the channel 19and the lugs 16 and 17.

It is obvious that this improved valve may be placed either verticallyor horizontally, or it can be in line with the inlet and outlet or inany other desired position without affecting the operativeness of thevalve.

This peculiar construction of the valve and its hinge connection avoidsthe necessity of using rivets or any otherfastening means, which areliable to become rusty, wear out, or ailect the operativeness of thevalve in any such manner.

The Valve herein shown and described embodies a removable self-adjustingclapper, which is a self-seater and which is drainable withoutinterference.

I claim as my invention 1. The combination with a pipe-section having anobliquely-cut-off discharge end and a closed-in portion or bridge abovesaid dis charge, of lugs rising from said bridge and a valve or closurefor the oblique discharge end having a stem engaging between said lugsand having bearings therein, substantially as set forth.

.3. A pipe-section having its discharge end cut obliquely to its axisand having a closedin portion or bridge above such oblique (lischarge,in combination with a valve seated upon the latter and having a stemseated between lugs upon the bridge-piece and having a transverse heador cross-piece engaging bearings in said lugs, the latter being beveledupon the front sides, substantially as set forth.

3. A pipe-section having an oblique discharge end and a closed-inportion forming a bridge above the same, lugs rising from said bridgeand having beveled front sides and rounded edges corresponding with thecontour of the pipe, one of said lugs being transversely perforated, anda transverse slot in the opposing lug, and a valve seated upon theoblique discharge end of the pipe and having a stem, engaging betweenthe lugs rising from the bridge and provided with a cross-piece engagingthe perforation and slotin said lugs, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.

FRANK \V. LEIDECKER.
